ro ALL WHoM rr MAY concerne; g i of Cincinnati, in the countv of Hamiltom'and State `oi Ohio, have` Beit known that I, EDWARD MYERS,

invented a new and improved Manner of Attaching Matcher-Heads to their Mandrels and I do hereby declare f l that the following is a full, clear, and exact .description thereof, which will enable others` skilled iu the art to"V make and use the same, reference being had tothe accompanying drawings, forming part oi'lthis specification,

t l in which* i Figure 1 is an end vienr of a matcher-head attached to its mandrel according to my` invention.

Figure 2 is a longitudinal section of the same, taken in the line :r x, fig. 1. V

Similar letters of reference in dicatolike parts. The object of this invention is to attach a matcher-head to its mandrel in such a manner` that it maybe applied and detached with the greatest facility, so that when it-is desired to use the entire width of the machine for planing or surfacing, the watcher head may be detached without any trouble oi" difficulty whatever, the mandrel remaining ixed or stationary. The ordinary plan is to removejhe matcher-head by taking its mandrel out of'it's bearings, Aor by having the bearings "in one casting, and lowering all out of the way byineans of screws or other mechanism. A. represents the mandrel of the ruatcher-head, which is provided with `a collar, BVthe,1atter being perrita-i` C represents the :natcher-head, which may be of the usual form, with ordinary` l cutters, a, attached to it. The collar B is on one end of the mandrel A, and is equal in diameter` to thc inner" `end of the matcl'rer-head C, the latter abutting against the former. D is a rod of cylindriealform, having` a f centrally through the matcher-head,`

head, b, at one end, and a screw, c, at tlie opposite end. This rod D passe the screw c fitting in a female screw, d, in the centre oi' the collar D, and in lineV with the centre of 'che man-i` drel A, as shown in g. 2. This 'screw-rod secures the matcher-head to the mandrcLpx-oventing any longitu-` dinal movement oi' the former, and a pin, E, which passes through the inner part of the watcher-head into` the V collar B, prevents the matcher-hcad from turning independent of the mandrel. ,ThispinE is rivetedlorrothcr-t. wise firmly securedin the collar, and a hole is made in the matcher-head, so that the pin may pass freely into it. From the above description it will be seen that by simply unscrewing the rod D, the matcher-head may be detached from the mandrel, and the trouble and inconvenience of detaehing or removingthe mandrel or adjust;

i ing it in any way, when the matcherehead is not required for use, avoided. This invention relates particularly to thc method of securing watcher fore disclaim attaching circular saws upon their mandrcls; but

What I claim as new, and desire to secure by Letters Patent, is 4The method herein described oi' attaching the matcher-head C to its mandrel by means oi' the screw-rod D ally through the said rnatcher-head, `and screwed into the collar B, one of whose. ends is provided t oi' the said watcher-head, substantially as set forth. EDWARD MYERS;

nontly secured on the former.
